Also burning up our "heat index," a supermodel mom, gisele bundchen, raising eyebrows this morning. She released a photo of her 8-year-old daughter with ears pierced. We asked that question, how young is too young. We ask that every day. Bianna. Reporter: Good morning, guys. The brazilian bombshell tweeted a photo of vivian brady. Accessorized in a necklace and a set of earrings. Some moms said, infants should not have their ears pierced. Others defend the act. Calling it nothing more than a cultural rite of passage. It cease no secret, photos of supermodel gisele bundchen, are known to turn heads. But it's this sweet snapshot of gisele and her 8-month-old baby girl that have people talking this morning. At issue, what appear to be the tiny gold studs in baby vivian's ears. The photo has received more than 58,000 likes. But the moms we spoke with were split over the piercing question. How young is too young? For me, personally, yes. I wouldn't do it to my daughter. You're going to end up getting them pierced anyway. Reporter: Bundchen, with two children to husband, tom brady, is no changer to controversy. In 2010, the supermodel made waves when she told "harper's bazaar u.K.," There should be a worldwide law that mothers should breast-feed their babies for six months. She sparked conversation as an advocate for all-natural, at-home births. Something she described in the documentary "the business of being born." At that moment, I felt like i could conquer the world. Reporter: As for the piercing controversy, some say the whole thing may come down to culture shock. What a lot of people don't realize, is this is something that's popular in gisele's culture. She's brazilian. And in latin america, it's common to get your infant daughter's ears pierced. Reporter: The question on many moms' minds this morning, is it safe so young? Our medical expert says yes. Nothing is without risk. But again, this is an area of the body that's, overall, has a low risk of infection. Reporter: This comes down to a cultural decision. I was ten months old when I had my ears pierced in russia. And babies have ears pierced. I called my mom and did research to ask if it was cultural. And she said the fact that I was bald and she didn't want people to think I was a boy. Had to nip that in the bud. My mother wouldn't let me get my ears pierced until college. Just depends. To each his own. To pierce or not to pierce. That is the question. So many things that babies go through that we don't talk about on this show, by the way.
